MacBook Pro (mid-2010) Internal USB HUB freezes/locks up
MacBook Pro (mid-2010) wilth the latest firmware, etc.
OS X 10.9.1
USB KVM to share keyboard and mouse with another computer
This has been working flawlessly until I upgraded to 10.9.1
The KVM uses the Scroll Lock key to toggle the input between the two computers
I switch back and forth many times a day.
Almost once a day now, all my input to my MBP will lock up when switching the KVM over.
The MBP track pad, keyboard, blue tooth Magic Mouse, KVM mouse and keyboard all become unresponsive.
I am assuming that the interal keyboard/track pad/blue tooth transceiver are all tied to an internal USB HUB.
The MBP is up and running and I can ssh into it. The only error message in the log is that the mouse device coming from the KVM is busy and it will be disabled. I have tried to close the lid for several minutes and then re-open, but it does not resolve the issue. I have tried connecting another USB mouse/keyboard during this time and it will not work. I have tried kill -HUP on the usbd and USBAgent processes. Everything stays unresponsive. The only way to resolve this condition is to reboot the MBP. Note: the KVM works find on the other computer when I switch it back and forth regardless of the state of the MBP.
I am suspecting that when this happens it is some how disabling the internal USB HUB, which if all the other devices are connected through it, nothing no longer works (but maybe I am crazy with that thought). Anyone have any insight? Is there a way to reset the internal HUB short of a reboot?
Thanks in advance!
